Wondering how to complete all the challenges? Well, just read here. This guide is specifically made for Mega Man X for iPhone, for guides to other versions of Mega Man and Mega Man X, I recommend using Google!

A very short review of the game
I loved this game for SNES and had to get it. I still love it. The controls are so-so, decent for a touch-based interface. The game is easier to make up for this (e.g. monsters don't respawn). Some things have changed however, mechanic-wise, which is not good (the route of the Boomerang Cutter is different). All in all a good game with terrible controls.
Worth it? I think so. If you like 2D-sidescrolling pew-pew madness this is something for you.

Before you start...One thing to keep in mind when working on gathering up achievements is, that when you got it, you got it. Same goes for collecting items. So when you have gotten what you came for in a specific stage, you can safely exit to the stage select and save the game.

These achievements are fairly easy to get and also award the least points. Don't worry about these as you will get them as you progress throughout the game. In the bottom of this guide you will find a short strategy guide to each boss, to help you defeat these.Clearing all stages (including the last Sigma Stage) and saving will not prevent you from going back and using that same profile to complete achievements.

Gathering these achievements, must to some degree be done in a specific order. The optimal order is to do take the dash first (Chill Penguin Stage), then go for the helmet (Storm Eagle Stage), now you can take the X-Buster (Flame Mammoth Stage) and the Armor Upgrade (Sting Chameleon Stage). This is because it is impossible to get the X-Buster upgrade with Helmet and Boots, and the Armor does not matter that much (reduces damage taken by 50%).Once you get an upgrade, you got it (on that save), so after claiming each upgrade you can safely exit the stage and do another if you wish to collect all the upgrades before you complete the stages.

BootsEasiest to get upgrade, go to the Chill Penguin Stage and complete it as you would normally, once you enter the cave and climb past the spinning wheels and bats, you meet a capsule, take it and voila.If you do not wish to get the shoes, you have to first talk to the man, and then jump over the capsule.

HelmetIn the Storm Eagle Stage, after the part with the floating platforms you must jump across, you will meet a tall metal pole, jump to the top of it, and slide down the other side. Jump off the platform at the bottom and reach the one to the right, go in and collect your price. You can now destroy rocks with a nice head-butt. This ability, together with dash, is required to collect the X-Buster upgrade.

Weapon

Weapon Upgrade location

Go to Flame Mammoth Stage, the first time you encounter the yellow platform with flames shooting up from underneath, you want to turn around and dash-jump off the yellow platform to the left as far as possible. Then with your helmet, head-butt the blocks and jump up till you see the capsule, collect your prize! Don't worry if you accidentally fall off after destroying a few blocks, it's still possible to get up there, even after destroying them all (this was not true for the original version of Mega Man X).

ArmorIn the Sting Chameleon Stage, you will after a few black-outs see a huge chunk of rocks on the right, here, jump up and go right. Eventually you will fight a miniboss. The easiest way to defeat him is to simply shoot him in the head with the X-Buster, and when he jumps, dash all the way to the other side, jump and shoot again, when he jumps, dash back to the spawning point, jump and shoot and so on. Repeat until he dies. When the miniboss is dead, a capsule will appear, claim your prize and move on.

It does not matter in which order you collect these, however, one requires an upgrade, the other a weapon.

The first one I collect is in the Storm Eagle stage. When you meet the rotating turret on a platform that moves up, shoot it, and take the platform up, shoot the glass and go right, kill the robot, go right, collect the Subtank.

The second one is found in the Flame Mammoth stage and require you to have the boots upgrade. The first area with flames shooting from the ground and miners throwing their pickaxes at you, jump to the top left platform. From here, dash and jump to the left. You will see a wall of breakable bricks. Jump on them till they break and collect the Subtank.

The third one is found in the Armored Armadillo stage, first time you drop down in a whole and a bulldozer chases you, run until it dies, go back to where it came from and collect the Subtank. Alternately, slide down the wall until the bulldozer starts moving, then jump up and wait until it has passed, then you can drop down and kill it or just go and collect your prize and wait for it to die.

The last one is in the Spark Mandrill stage and requires the Boomerang Cutter. In the beginning of the level, move down and right as much as you can, and then when standing closest to the last wall you reach, jump and fire the Boomerang Cutter. This should collect the Subtank.

Each of the Maverick stages contains a Health Boost heart. In the order that I normally collect them:

Flame Mammoth StageIn the area with the flame from the bottom and the miners throwing pickaxes, on the bottom level, move all the way to the right, collect your heart.

Chill Penguin Stage - Requires Fire Wave Weapon UpgradeOn top of the platform you meet after finding the first robot, destroy the bunkers using the Fire Wave weapon. You can get there either by jumping in the robot and then exiting it and jump up onto the "roof" of the cave, or walk through the cave and jump up there normally.

Spark Mandrill Stage - Requires Boots Upgrade or Boomerang CutterThe first ladder you meet that leads to the remaining part of the level, jump up on the right side wall, dash jump away from the wall and up onto the platform and collect the heart. Alternately you can jump and use the Boomerang Cutter.

Storm Eagle Stage - Requires Boots UpgradeIn the first map, on the highest left-most point of the elevator, dash-jump to the left. Collect your heart.

Launch Octopus StageWhen you find the second whirlpool that leads up to a submarine, jump up and onto it. Shoot the glass "eye" until it falls down, let yourself fall down with it. Walk right, defeat the worm, go to the right and collect the heart.

Armored Armadillo StageThe second time you jump down and face a bulldozer, kill it (with auto-fire cheat this goes fast), move right until you meet a platform, jump up there and collect the heart. You can easily see it.

Sting Chameleon Stage - Requires Boots UpgradeBefore the cave, where the miniboss entrance is right above you, slide down the wall instead. Here you will see a wall of breakable bricks. Break it, go as far right as you can, then dash-jump to the right onto a platform and collect the heart.

Boomer Kuwanger Stage - Requires Boomerang Cutter or Shotgun Ice+Boots Upgrade+Weapon UpgradeYou can't miss the location of this heart when walk through the stage, and you need to complete it before you can collect the heart. Use the Boomerang Cutter to collect it.On the SNES, this could also be collected using a fully charged Shotgun Ice shot with the weapon upgraded, to make a skateboard, and from that, dash jump out and up onto the platform. However, it's not that easy with the touch controls so I haven't gotten around doing it on my own iPhone sadly.

Boss WeaknessesAchievements: Emperor of Ice, Tsar of Electricity, General Steel, Captain of the Seas, Demon of Dimensions, Master of the Forest, Prince of the Skies, Oligarch of Oil, Wall of Terror, Carnivorous Tank, Loyal Wolf, End of an Era, Dawn of Destiny.Use the below listed weapons of choice to defeat the bosses and obtain the achievements.NOTE: It is only the LAST shot that counts, so beating the bosses with a different weapon and then finishing them off with their weakness will still grant you the achievement.NOTE: You do not have to gather these achievements during your first run through of the Maverick bosses, you will face them all again during the Sigma parts and can kill them here (so you don't have to go back and redo bosses).

Obtaining and using the Hadoken (Hadouken)Achievement: Hadoken!

Getting your hands on the most powerful weapon in the game is quite simple, in comparison to the original: Gather all 8 Health Boosts, all 4 Subtanks, all 4 body upgrades and kill all 8 Maverick bosses. Basically, complete everything up until Sigma.

Then go to Armored Armadillo stage, and on the last wagon (the 3rd one), charge up for a super shot, release it while you in the middle of the screen, shoot some small shots to kill the birds ahead of you, and once the wagon is in free air and reaches its highest point, dash jump off to the right, jump up and take the Hadoken upgrade.

To use Hadoken, Press Down -> Left or Right -> Fire

NOTE: To be able to use Hadoken you MUST have full life.

HINT: An easy way to fire Hadoken is by sliding your finger the down button towards the middle of the screen really quick and then click fire. Remember that the down button dashes towards your target, so don't stand too close when trying to fire this weapon.

While most of these are self-explanatory from the list of achievements in the Game Center, some of them are not.

Bubbly BatIn the Armored Armadillo Stage, instead of taking the mining carts (one-wheeled thing with spikes in the ends), walk. You will meet a big black bat, kill it, and you will receive your reward for killing the Batton M-501.

Flashy FireflyIn the Spark Mandrill Stage, in the area where the light flashes and those flies cross the screen illuminating a path behind them, that's a Hotarion. Kill one of these to get the achievement. Walk through this area a second time once you have learned when and where they spawn (always the same places).

Oil Well Sealer - Requires Boomerang CutterShoot at Flame Mammoth with the Boomerang Cutter until his trunk falls off.

Daring Collector - Requires Weapon Upgrade+Chameleon StingIn Sigma's Palace, Pt. 3, when you get to a long row of spikes with items on top, charge up for an upgraded shot of Chameleon Sting, this will allow you to take no damage when you walk across the spikes and collect the items.

Merciful HunterChoose whichever stage you find the easiest and walk through it. Remember, you can lose life, just not fire any shots. Remember, Launch Octopus Stage is impossible to do this achievement in because of the worm.

Heartless HunterThis achievement is easiest to do on either Spark Mandrill or Boomer Kuwanger. Use Shotgun Ice to kill Spark Mandrill or Homing Torpedo on Boomer Kuwanger and you should get this in the first try. It might not be impossible for definitely very hard on bosses like Chill Penguin, Armored Armadillo, Launch Octopus, Sting Chameleon and Storm Eagle since they all have a way of avoiding your attacks.

S-A Class HunterPractice in avoiding the bosses skills. This one is definitely the hardest of all the 60 Achievements.The Intro Stage

The Intro stage does not exactly contain any achievements, however, there are 20 bonus challenges to do for the completionist! Completing the challenges will make Doctor Thomas Light appear for you and tell you how awesome you are and invite you to complete the rest of the achievements above. In addition you will notice that as you complete the challenges, you obtain little pieces of a picture, once finished, you can tap the upper left corner of the screen to see the picture of the Mavericks in full screen.I suggest running through the Intro Stage several times (at least 10 :p), and every time you complete it, pick a few of the challenges you haven't done yet and try to do those (I don't know about you but I failed a few times).The hardest challenge for me was to die to Vile. What you do is that you make sure to have only 1 life left when you face him, then as he shoots and attacks you, wait until the light spark is close, then jump into him and die.The other one that could be hard is the speed one. A tip is to stand behind the 'copters when killing them (just run through them). Then you can continue onwards more quickly.The item collection consists of 2 items, just after the first giant bee, slide into the hole and you will find them. Pick them up and you are good to go.

Time Attack - New game mode added after release

Time AttackThis game mode had the potential to be interesting, but it isn't really.Especially because I'm pretty sure they messed up the ranking of it, so the longer you take, the higher you rank... What a killer. Personally I don't like this game mode, mostly because it doesn't really add any value to the game (for me). There's not much to say about it either, however, a few short sentences about it follows:The game mode is all about speed. At the same time however it is vital that you kill stuff and collect the green balls that creatures drop.Once you start playing this mode you have probably completed the game already and started working out the best ways to clear certain stages. Knowing what comes next helps a lot, especially in stages like Chill Penguin and Armored Armadillo where you often face flying monsters. When you know where they are you can shoot them so that the items fall to the ground and you can pick them up as you dash past, this will improve your speed a lot!

Survival ModeTime has passed and the last of the three "Ranking Modes" have been released (maybe we'll see more in the future?). Survival mode is pretty simple: You select a profile ("Save Data") and then you have whatever upgraded or not version of MegaMan. You can not get life or shots back, so eventually (given that you take damage and use shots) you will die, and it is all about getting as far as possible. The maps are modified versions (basically much longer) of the standard maps with a mixture of monsters serving as obstacles. For every fifth 'floor' there is a boss (Floor 5, 10, 15 and so on), I recommend using the Boss Weakness Table earlier in this post to see what weapon you should fight them with.As for the floors: Play this mode over a few times and you will eventually learn the maps and positions of monsters, allowing you to get further.Good luck!
